<h1 id="purpose">Purpose</h1>
<p>The BSP (Board Specific Package) drivers are parts of the STM32Cube package based on the HAL drivers and provide a set of high level APIs relative to the hardware components and features in the evaluation boards, discovery kits and nucleo boards coming with the STM32Cube package for a given STM32 series.</p>
<p>The BSP drivers allow a quick access to the boards’ services using high level APIs and without any specific configuration as the link with the HAL and the external components is done in intrinsic within the drivers.</p>
<p>From project settings points of view, user has only to add the necessary driver’s files in the workspace and call the needed functions from examples. However some low level configuration functions are weak and can be overridden by the applications if user wants to change some BSP drivers default behavior.</p>

<ul>
<li>General updates to fix known defects and enhancements implementation.</li>
<li>Update BSP_SRAM_Init function to add initialization for WriteFifo and PageSize parameters.</li>

<ul>
<li>ADC configuration updated according to latest HAL ADC changes.</li>
<li>Fix ADC clock configuration:
<ul>
<li>Use peripheral clock (per_ck) as ADC kernel source clock.</li>
<li>The per_ck clock is set to HSI internal clock (64 MHz).</li>
<li>Input ADC clock divided by 2 giving an ADC clock of (64MHz / 2) = 32MHz which is within the ADC specification.<br />
</li>
</ul></li>
</ul></li>
<li>Improve BSP_SDRAM_Init and BSP_SDRAM_DeInit error management.</li>
<li>Fix BSP_NOR_MspInit to remove extra GPIOs settings.</li>

<ul>
<li>New settings are backward compatible for STM32H743I-EVAL rev.B.</li>
</ul></li>
<li>Increase DMA2D timeout value in stm32h743i_eval_lcd.c files functions LL_FillBuffer and LL_ConvertLineToARGB8888.</li>
<li>Updates to improve BSP QSPI driver:
<ul>
<li>Use DTR mode instead of STR.</li>
<li>Use 4-Bytes addressing mode.</li>
<li>All instructions are sent on 4 lines (same for data).</li>
<li>Fix BSP_QSPI_GetInfo to return correct sectors size and erase sectors number.</li>
</ul></li>
<li>Remove workaround in BSP_AUDIO_OUT_Init for MDK-ARM:
<ul>
<li>Audio Volume no more divided by 2 in case of MDK-ARM IDE (no more need of this workaround as the issue is fixed by the new PDM libraries v3.1.0)</li>
</ul></li>
<li>Update BSP_SD_Init API to use a clock divider of 2 instead of 1 (allowing to have an SDMMC clock of 50MHz)</li>
</ul>
